Maybe one day we'll reach the point where enormous dollar amounts for baseball contracts cease to stagger us, but today is not that day.

New York Yankees free-agent-to-be Robinson Cano is reportedly seeking a deal worth at least $300 million dollars this offseason, as was first reported by ESPN's Buster Olney and confirmed by multiple other sources. Cano is represented by Roc Nation, the agency run by Jay-Z.

Of course, just because this number has been thrown out there -- Olney reported Cano was looking for a 10-year, $305 million deal -- doesn't mean Cano will actually get that money. It's part of the negotiation process, a process that has increasingly become more and more public over the years.

If Cano should land that kind of deal -- or anything within $30 million of that -- he would be the owner of the richest contract in baseball history. His Yankee teammate Alex Rodriguez currently owns that designation, with the 10-year, $275 million deal he signed in December 2007. A-Rod also owns the second-biggest deal, the 10-year, $252 million contract he signed with Texas in December 2000. Albert Pujols is third on that list with the 10-year, $240 million deal he signed with the Angels in December 2011.

Cano will turn 31 on October 22. He's been arguably the most consistently excellent (and durable) player in the game lately; he's had at least 634 plate appearances each of the past seven years and is averaging 28 homers and 102 RBIs over the past five years. He's a five-time All-Star and a three-time Gold Glove winner.

He will land a massive deal somewhere. But 10 years for a 31-year-old? The almost immediate declines of recent free agents Albert Pujols and Josh Hamilton certainly won't help Cano's case.
